Using a display device with a transparent display to capture information concerning objectives in a screen of another display device

Abstract

Information in a screen of another display device such as a television or a computer monitor can be captured by a display device including a transparent display, a camera unit, an input unit, and a control unit. The transparent display allows a user to view the screen through the transparent display. The camera unit produces screen images corresponding to the screen. The input unit produces selection parameters in response to a selection operation corresponding to a virtual image of the screen seen through the transparent display. The control unit determines objective(s) in the screen according to the screen images and the selection parameters. The control unit may transmit the objective data corresponding to the objective(s) to the transparent display, thereby enabling the transparent display to display objective-related information corresponding to the objective according to objective data.

         8 . The display device of  claim 7 , wherein the control unit determines the indicating direction of the user by determining the direction of a vision line of the user through the one or more user images. 
     
     
         9 . The display device of  claim 1 , wherein the transparent display comprises at least one of a transparent active-matrix organic light-emitting diode (AMOLED) display and a transparent liquid crystal display (LCD) display. 
     
     
         10 . The display device of  claim 1 , further comprising a storage unit storing one or more sample objective data, wherein the control unit recognizes the one or more objectives by analyzing the one or more screen images according to the sample objective data when determining the one or more objectives. 
     
     
         11 . A display method, comprising:
 a display device comprising a transparent display allowing a user to view a screen of another display device through the transparent display;
